"scientific knowledge builds upon previous knowledge." which situation best illustrates the statement? a) repeating the experiment of another scientist. b) tina ignoring non-supportive results of an experiment. c) the development of the modern cell theory over the course of hundreds of years. d) tim classifying his experiment a failure because his results do not support his hypothesis.

The answer is C. This is because the discovery of the cell and its organelles began with the discovery of the microscope in the 17th century. As powerful microscopes were developed over time, the cell organelle become discover-able by different scientists. As other developments emerged, they enabled tagging of elements, hence monitoring of biochemical pathways also became possible.

good thing- during decomposition the organic molecules in organic matter are broken down into simpler organic molecules that require further decomposition or into mineralised nutrients

bad thing- it can be harmful in crop productivity

his research revealed two genetically different groups of prokaryotes, which justified splitting kingdom monera into two kingdoms. the genetic and cellular differences were so great, that these two kingdoms were eventually placed into different domains in the current three-domain system.
